This strategy made it possible for the first pitcher to return to a mound after the replacement pitcher (usually a lefty) pitched to the next batter. It was popularized by Paul Richards, and used most often by Indians manager Alvin Dark and Cardinals manager Whitey Herzog. It became largely obsolete with the advent of deeper bullpens and shorter benches.

Either the pitcher played in the field because he truly was the best available player or for some other unclassifiable reason.

These lists include only pitchers who played in the field, or were listed in the starting lineups at non-pitcher positions. Pitchers who merely pinch-ran (many) or pinch-hit (Rick Honeycutt) for the listed DH are not included. Same goes for pitchers who started in the majors at other positions (e.g., Brooks Kieschnick) and players who started in the majors as pitchers, but moved to other positions (e.g., Babe Ruth).

Also, I restricted the lists to games from 1957 or later. The play-by-play for games from 1956 and earlier are not easily available, and finding them would be quite time-consuming. At some point in the future, I may add such games.
